[comp.infosystems] Headcount model for internal cust. support?

Does anybody have a reasonable staffing/headcount model for figuring out
how many service/support people it takes to properly service a given 
population of desktop computers?  

As a new manager of End User computing (with no previous manager in this
position!), I'm struggling with the best way to empirically show that I
need more than one person to service/support a population of 750 Macs & PC's.
Our Customer Support division has wonderful models for *their* base of
product support engineers and FE's, but they *also* have MTBF and MTTR data
on all the equipment -- I can't get Apple or any of our PC suppliers to 
divulge these magical numbers, so the models which uses these wonderful
numbers aren't useful to me.

Anybody have any ideas?
